Descripción

COMBO FA6B20N + FA1A60N

• Fabricante: Fuji Electric
• Código: FA6B20N
• Marking: 6B20

• Descripción:
~ LLC Current Resonant Control IC ~
- The integrated startup circuit achieves downsized power supply and lower power consumption.
- Operating mode can be switched between normal operation mode and low standby mode.
- ”Auto standby operation” and “Standby operation by external signal” are selectable.
- During the low standby mode, standby power is lowered by the burst mode operation.
- Integrated input filter X-capacitor discharge function decreases loss due to discharge resistance.
- Low consumption current, 0.80mA (Vcc quiescent current).
- Integrated high-side and low-side drive circuits, which can be directly connected to the power MOSFET and operates with 50% duty cycle.
- Various protection functions: overcurrent (IS pin), overload (CA,FB pin), overvoltage (VCC pin), overheat and protection by external signal (MODE pin).
- Integrated level-fixed brown-in/out function (VH pin)
- Various mode selection settings can be made: overcurrent protection (detection by IS pin) delay time setting, operation setting in standby mode, and adjusting output power switching to standby mode.
- Under voltage lock out function (VCC,VB pin)
- Encapsulado SOP-16

~ Corrector de Factor de Potencia (PFC) ~
- Operating mode can be switched between burst mode and normal mode by communication signal from “FA6B20N”. It helps to improve light load efficiency.
- Combining with “FA6B20N”, operation is optimized according to line voltage and distortion of line current is improved for wide input voltage range.
- Low standby power due to no input voltage detection resistors
- High-precision over current protection: 0.6V±2%
- Improved power efficiency at light load by frequency reduction
- Reduced audio noise at start up by overshoot reduction and dynamic OVP
- Low current consumption by CMOS process,
- Start-up: 250µA(typ.), Operating: 0.8mA(typ.)
- Drive circuit for power MOSFET, peak current: source 500mA, sink 1000mA
- Protects the output electrolytic capacitor by the double OVP function, even if a fault happen in the output detection.
- Short protection at feedback (FB) pin
- Under-voltage Lockout
- Restart timer
- Encapsulado SOP-8
